SAFETY-RAZOR.

Application filed April 13, 1920.

To all whom it may concern:

Be it known that I, JOHN J. CA'rRoN, a citizen of the United States, residing at Bonham, in the county of Fannin and State of Texas, have invented certain new and useful Improvements in Safety-Razors, of which the following is a specification.

This invention relates to new and useful improvements in razors.

The invention has particularly to do with a razor having a longitudinally reciprocating blade arranged to be operated by the fingers of the person shaving with the razor. The particular result sought is simplicity, compactness and efiiciency in operation, together with certain other novel features which will be hereinafter more particularly pointed out.

In carrying out the invention a reciprocating blade carriage is mounted on a support which latter carries a guard. The blade is readily detachable from the carriage and acts as a means of preventing the disengage ment of the carriage from the support until the blade is removed. Such arrangement, however, is very satisfactory as by removing the blade the carriage may be removed from the support and the. parts thoroughly cleansed. An operating member is provided and connected with an actuating element which is connected with the carriage so that by manipulating the'operating member the actuating element is placed in motion and the carriage reciprocated. Details of construction will be hereinafter more particularly pointed out.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown, and wherein:

Figure 1 is an elevation of a razor constructed in accordance with this invention,

Fig. 2 is a side elevation of the device shown in Fig. 1,

Fig. 3 is a plan view of the carriage support or head of the razor,

Fig. 4 is a face view of the carriage,

Fig. 5 is a rear elevation of the carriage,

Fig. 6 is an enlarged plan view showing the carriage andv a portion of the head. the

blade being removed,

Fig. 7 is a plan view of the head and component parts with one of the blade retaining wings in section,

Specification of Letters Patent.

Patented Oct. 25, 1921. Serial No. a73,sa1.

Fig. 8 is a sectional detail of the handle and operating member, and

F1g. 9 1s a cross sectional detail on the line 9-9 of Fig. 7.

In the drawings the numeral 10 designates a head or support which has an upstanding flange 11 at each end. Along its lower edge the head has a'depending trough 12 the; front edge of which is formed into a plurallty of guard teeth 13. The trough is provided with longitudinal slots 14 having notches 15 in their upper sides as is clearly shown in F 1g. 3. The head is fastened in a suitable manner to a curved shank 16, which is fitted into the end of a sleeve 17. The sleeve is fitted in the end of a handle member 18.

A blade carriage 19 is provided at each end with inturned overhanging wings 20. The carriage is bent longitudinally upon itself along ts top edge to provide an apron 21 depending on the rear side of the carriage. A pair of ears 22 are upset from the upper portion of the carriage and bent downwardly between the base or body of the carriage and the apron. Along the lower edge of the carriage a pair of ears 23 are .bent upward on the rear of said carriage.

The carriage is engaged over the upper edge of the head 10 so that the apron hangs on the rear side of the edge and the upper cars 22 hang on the upper edge of the head. The lower ears 23 are positioned so as to pass through the notches 15, and thus when the carriage is moved to the left (Fig. 3) said carriage is fastened or held against displacement from the head and in order to remove the carriage it must be slid along so that the ears 23 may be lifted through the slots 15 as will be obvious.

Asafety razor blade 24 is inserted in the carriage from the upper end of the latter so as to engage under the wings 20. The razor blade which is employed has laterally extending lugs 25 at its upper corners and the wings 20 are notched out at 20' so as to receive these lugs and thus limit the downward movement of the blade and also to control the proximity of its cutting edge to the teeth 13 of the guard. It will be noticed that the left hand flange 11 ofthe head (Figs. 3, 6 and 7) is provided with a pro jecting stop 11' and this stop is located in the path of the adjacent lug 25 of the razor blade and limits the reciprocation of the carriage in that direction. By this means the carriage is; stopped before the.,ears 23 register'wit-h the notches in as will be evidenced from Fig. 7, thus preventing the disengagement of the carriage from thehead until the blade 24 is removed. This is a very simple and convenient arrangement and permits the parts to be quickly disassembled by simply removing the blade 24.

A bell crank lever 26 is mounted on a pivot stud 27 seated in the shank 16. The lever has one end engaging in a notch 28 inthe lower edge of the -"apron'21i T heother end of the lever is pivoted tothe forward end of a link 29 which has itsiend pivoted in an eye 30 projecting from oneside ot'a collar 31. The collar is concaved andfitson the will be obvious.

sleevel? so asto slide freely. The sleeve 17has a shoulder 17 which limits the inward or downward movement'of the collar, It will be seen that by reciprocating the collar the lever 26 is swung through the agency of'the link, 'wherel iy' the carriage'lt) audits blade are reciprocated. For ass st ing inthis operation the sleeveis provided with a slot 32 on'each side and a transverse pin 33 fastened within the collar passes through this slot. A coiled spring'flt is ,eon-' fined between the pin and the bottom of the sleeve When the-collaris pulled inward or toward its shoulder 17- the sp ing'islf compressed and thus assistsin the outward movement of the collar. In using the razor the operator grasps the handle l8and places tl'iejcollar'either bQ-' tween two of his fingersor between the index finger his thumb; By P llin 'inward on the-collar the-blade and carriage are shifted to the right and by releasing the.

collar, the spring which has been compressed returns the collar whereby the carriage and blade are swung or shifted to the left. By

manipulating the collarrapidly the carriage,

and blade-are operated or"reciproeatedwith suflicient rapidity to carry out a satisfactory cutting action. After the face has" been lathered the operator draws the 'azor down his face and uses 1 the same in substantially the same manner as an ordinar jsa'tety razorythe guard teeth 13 combing the beard and assistingun the-shaving operat on is After the razor lias been' used it ma bequickl'v taken apart by merely p ulling outbladezidr and lifting off" the carriage as has beenexplained. The parts may be thoroughly cleansed and replaced;

The trough 12 provides clearance under the cutting edge dream-mp blade and also permits a. free passage of the latherso that the razorwill not be'elogged up. The slot '14 also facilitates the escape of the lather and cuthairs. i
